Q. How can I tell if any of my CPU cores have been parked?

A. Windows 7 and Windows Server 2008 R2 can park specific cores on a system. When a core is parked, the core is essentially in sleep state. To see which cores are parked, you can launch the Resource Monitor, which is located in the Accessories, System Tools folder. Select the CPU tab, and in the CPU summary region you can see the if a core is parked, as shown.
